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 now, let’s dive into this! That dictionary definition is a mouthful, isn't it? Let’s break it down and make it nice and clear. Think of it like this: What is protein? Essentially, proteins are the builders of your body – truly! They’re like tiny little bricks that help you grow, repair, and function perfectly. Let's unpack that definition piece by piece: “Any of numerous large, complex molecules…” – That means there are many different kinds of proteins, each with a specific job to do. They’re complicated structures! “…naturally-produced…” - Your body makes them! It's an amazing process. “composed of one or more long chains of amino acids…” – Now this is key. Proteins are built from smaller units called amino acids . Think of them like LEGO bricks, all linked together. There are twenty different kinds of these "LEGO" blocks! “…in which the amino acid groups are held together by peptide bonds.” - These amino acids link up to form long chains – and they do it with special connections called peptide bonds . It’s like a strong glue holding everything in place. So, to put it simply: Proteins are huge molecules made of lots of smaller amino acid building blocks linked together by chemical bonds. Think about these examples: Your muscles need protein to get stronger! 💪 Enzymes – which speed up reactions in your body - are proteins! 🧪 Hormones, like those that control growth and mood, are also proteins. 🧠 Do you have any questions about this? Don’t be shy, let's explore it further!

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! 😊
