The shape of a protein molecule resembles BEADS ON A STRING.
Proteins are macro molecules that are formed from amino acids. There are different types of amino acids, thus, different amino acids combine together to form different types of protein. This means that, proteins are formed from sequences of amino acids; they are long chains of different amino acids, that is why, they are likened to beads on string.
The structures of proteins are in three dimensions, they are primary, secondary and tertiary structures. The primary structure refers to the sequence of the amino acids in a protein. The amino acids in the primary structure are linked together by peptide bonds.
Your answer would be CCI4. CCI4 is bonded by sharing electrons, which means it is covalent bonding
Answer:
- Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. or
- Starch is a long-chain polymer of glucose molecules joined together. or
- A starch is a complex polysaccharide made up of a large number of glucose units joined together by glycosidic bonds.
Explanation:
starch, a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents.
Starch is amongst the most abundant plant products and is a mixture of two polymers, amylose and amylopectin. During food processing starch is transformed by hydrothermal treatments. ... The structure of starch is also influenced by specific and non-specific interactions with other food constituents and ingredients.
Answer:
O D. It has an -OH group attached to the end of the molecule.
Explanation:
Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule
- R is aryl or alkyl group
- OH is hydroxyl group
