Definition: Any of numerous large, complex naturally-produced molecules composed of one or more long chains of amino acids, in which the amino acid groups are held together by peptide bonds.

Alright class, settle down, let’s take a look today, At something vital – proteins, come what may! That dictionary definition, it's quite detailed and true, Let’s break it down for you, me and you. “Large, complex molecules,” that's the starting phrase, Building blocks of life in countless ways. Now “amino acids” are the key, you see, Like little LEGO bricks – a fundamental decree! These amino acids, one by one they go, Linked together with peptide bonds, you know! Think of it like a chain, long and strong and bright, Holding them together with all their might. So proteins are basically chains, built with care, From these amino acid links beyond compare. They do so much - from building muscle strong, To enzymes that help reactions along! Do you have any questions? Let’s discuss this further and make sure it sticks in your minds! 😊
