Which are the three main types of lipids

Biology
2 answers:
maxonik [38]3 years ago
4 0

Answer:

The three main types of lipids are - triglycerides, diglycerides, and steroids.

Explanation:

Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.

An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.

A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.

Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.

Answer:

Triglycerides, diglycerides, and steroids.

Explanation:

Lipids may be defined as the organic compounds that contain fatty acids and their derivatives. Lipids are generally insoluble in water but easily dissolve in the organic solvents.

The three common lipids are triglycerides, diglycerides, and steroids. Ester can be derived by the reaction between the glycerol and three fatty acids known as  triglyceride. Glyceride that consists of 2 fatty acid chains liked with  a glycerol molecule by the ester bond is known as diglyceride. Steroids are the biologically active compounds that contain four rings in its structure arranged in the fixed configuration.

Thus, the correct answer is triglycerides, diglycerides, and steroids.

Describe the most common molecular mechanism for recessively inherited human genetic diseases such as cystic fibrosis.
Marta_Voda [28]

Answer:

Explanation:

cystic fibrosis is an autosomal recessive disorder. When the child receives the defective gene from both of his parents, he suffers from cystic fibrosis. Because his parents are carriers. In recessive genetic disorder, the genes will be expressed when both recessive genes are present in one person. The person suffering from this disease have a lung infection and pancreatic dysfunction.  

In this cystic fibrosis, genes are located in chromosome 7. The effective gene is the CFTR gene. The CFTR gene is present in the DNA and by transcription, this forms CFTR protein. This is a channel protein and transports chloride ion.

This CFTR protein transports chloride ions and it makes a balance in the cell membrane. These genes are commonly present in the epithelial cells. Outside the epithelial mucus is present to keep the cells moist.

The epithelium gets a lack of water and chloride due to the defect. Therefore cells need CFTR proteins also. This causes lung infection and pancreatic disorder.

What type of tissue comprises the bulk of the myocardium
ycow [4]

Answer:

Cardiac muscle tissue

Explanation:

Myocardium or heart muscle is a special type of muscle (differ than striated and smooth) and it is the main tissue of the walls of the heart.

Heart muscle consists of individual heart muscle cells (cardiomyocytes) which are joined together by intercalated discs. It also contains  collagen fibres and other substances that form the extracellular matrix.

Heart muscle has a "special" mode of contraction: action potential triggers the release of calcium ions from the cell's internal store, the sarcoplasmic reticulum.

Which synapse(s) are specifically responsible for the sensitization of the withdrawal response?
qaws [65]

The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.

The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.

By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.

Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.
