Question

proteins

1. define proteins:
2. amino acids:

• the monomer building blocks of proteins are
• there are ____________ different amino acids
• draw the basic structure that all amino acids
• what makes amino acids different?
• amino acids form:

Explanation:

1. Proteins are large, complex molecules composed of amino - acids. They play many crucial roles in the body, such as catalyzing biochemical reactions (enzymes), providing structural support, and facilitating transport of molecules.
2. There are 20 different amino - acids that are commonly found in proteins. All amino - acids have a basic structure consisting of an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a side - chain (R - group) attached to a central carbon atom. The side - chain (R - group) is what makes each amino - acid different. Amino - acids form peptide bonds with each other to create polypeptide chains, which then fold into functional proteins.

Answer:

1. Proteins are large, complex macromolecules made up of amino - acids that perform a wide variety of functions in living organisms.
2. 20; The basic structure of an amino - acid has an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R - group attached to a central carbon. The R - group makes amino - acids different. Amino - acids form peptide bonds.
