Answer: 8- D
9- C
Explanation: always remember the number above is the atomic number
Answer: carbohydrates is composed of amino acids
Explanation: carbohydrate functions as an energy giving food in the body. Examples are rice, casssava and maize. The molecular structure of carbohydrate is (CH20)n. Carbohydrate has three subtypes:
(1) Monosaccharides: They are simple sugar and consists of a number of carbons(C) which ranges from 3 to 7.
(2) Disaccharides: They are formed when two Monosaccharides undergo a dehydration reaction which is also known as condensation reaction. thanks
(3) Polysaccharides: They consist of a long chain of branched or unbranched
Monosaccharides Monosaccharides linked by covalent bonds.
Carbohydrates is not composed of amino acids but rather protein is composed of amino acids.
Answer:
By binding sugars on the outside.
Explanation:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
Have a great day!
